我对 node.js 和 nginx 世界很陌生。我正在尝试安排一个简单的设置，它有 2 个节点服务器（只是一个简单的 hello world）和 nginx 作为负载均衡器。我正在使用上游来指定我的节点服务器，然后告诉代理（nginx）将请求传递给组中的任一服务器。

问题是当我尝试下面的配置去 localhost:81 时，当我应该从节点获得“hello world”消息时，我会收到欢迎来到 nginx 页面。

有什么我想念的吗？我正在使用 Windows 进行设置。这应该是一个问题吗？

下面我包括节点服务器和 nginx.conf

var http = require('http');
http.createServer(function (req, res) {
  res.writeHead(200, {'Content-Type': 'text/plain'});
  res.end('Hello World port 1337\n');
}).listen(1337);
console.log('Server running at http://127.0.0.1:1337/');

这是我的第二个节点示例

var http = require('http');
http.createServer(function (req, res) {
  res.writeHead(200, {'Content-Type': 'text/plain'});
  res.end('Message from Node running on port 1665\n');
}).listen(1665);
console.log('Server running at http://127.0.0.1:1665/');

upstream这是 nginx 配置文件.. 除了部分和location部分外，我与默认设置没有太大变化

worker_processes  1;

#error_log  logs/error.log;
#error_log  logs/error.log  notice;
#error_log  logs/error.log  info;
